Comparative Evaluation of Pediatric Rotary Files and Hand Files in Primary Molars

The goal of this clinical trial is to evaluate and compare the efficacy of Kedo-Nano Plus rotary files, Kedo-S Square rotary files, and manual K-files for biomechanical preparation during pulpectomy of primary mandibular molars in children aged 5-8 years. The main questions it aims to answer are: * Does the use of Kedo-Nano Plus and Kedo-S Square rotary file systems result in better obturation quality compared with manual K-files during pulpectomy of primary mandibular molars? * Does the use of Kedo-Nano Plus and Kedo-S Square rotary file systems reduce postoperative pain compared with manual K-files following pulpectomy? Researchers will compare Kedo-Nano Plus rotary files, Kedo-S Square rotary files, and manual K-files to determine their effect on obturation quality and postoperative pain. Participants will: * Undergo clinical and radiographic evaluation of primary mandibular molars requiring pulpectomy. * Be randomly allocated to one of three instrumentation groups: Kedo-Nano Plus rotary files, Kedo-S Square rotary files, or manual K-files. * Receive pulpectomy treatment using the assigned instrumentation technique. * Undergo radiographic assessment of obturation quality following treatment. * Have postoperative pain assessed using the Wong-Baker Faces Pain Rating Scale at 6, 12, 24, and 48 hours after treatment.

Effect of Graphene Oxide on Vital and Non-Vital Primary Teeth Compared to the Conventional Techniques

The null hypothesis of the current study suggested that there will be no significant difference regarding the effect of Graphene Oxide (GO), Lesion sterilization and tissue repair (LSTR) and Zinc Oxide and Eugenol on the clinical and radiographic success rate of non-vital pulpotomy of primary teeth and that there will be no significant difference regarding the effect of Graphene Oxide (GO), MTA and Zinc Oxide and Eugenol on the clinical and radiographic success rate of vital pulpotomy of primary teeth. The children (n=126) will be divided randomly into 2 arms; each arm has 3 groups, according to the type of pulp therapy dressing, medicament,t and technique of its application as follows: First Arm (Vital Teeth) Group 1: will receive Graphene Oxide using the vital pulpotomy technique (study group, n=21) Group 2: will receive MTA using vital pulpotomy technique (study group, n=21) Group 3: will receive Zinc Oxide and Eugenol using the vital pulpotomy technique (control group, n=21) Second Arm (Non-Vital Teeth) Group A: will receive Graphene Oxide using the non-vital pulpotomy technique (study group, n=21). Group B: will receive LSTR using the non-vital pulpotomy technique (study group, n=21). Group C: will receive Zinc Oxide and Eugenol using non-vital pulpotomy (Control group, n=21). Clinical and radiographic success will be assessed as primary outcomes, while pain, patient satisfaction,n and time of procedure will be assessed as secondary outcomes.
